The relative importance of households as a source of variation in child malnutrition: a multilevel analysis in India.

BACKGROUND: Child malnutrition remains a major public health issue in India. Along with myriad upstream and social determinants of these adverse outcomes, recent studies have highlighted regional differences in mean child malnutrition rates. This research helps policy makers look between urban and rural communities and states to take a population-level approach to addressing the root causes of child malnutrition. However, one gap in this between-population approach has been the omission of households as a unit of analysis. Households could represent important sources of variation in child malnutrition within communities, districts, and states. METHODS: Using the fourth round of India's National Family Health Survey from 2015 to 2016, we analyzed four and five-level multilevel models to estimate the proportion of variation in child malnutrition attributable to states, districts, communities, households, and children. RESULTS: Overall, we found that of the four levels that children were nested in (households, communities, districts, and states), the greatest proportion of variation in child height-for-age Z score, weight-for-age Z score, weight-for-height Z score, hemoglobin, birthweight, stunting, underweight, wasting, anemia, and low birthweight was attributable to households. Furthermore, we found that when the household level is omitted from models, the variance estimates for communities and children are overestimated. CONCLUSIONS: These findings highlight the importance of households as an important source of clustering and variation in child malnutrition outcomes. As such, policies and interventions should address household-level social determinants, such as asset and social deprivations, in order to prevent poor child growth outcomes among the most vulnerable households in India.

Multilevel analysis of geographic variation among correlates of child undernutrition in India.

Prior research has identified a number of risk factors ranging from inadequate household sanitation to maternal characteristics as important determinants of child malnutrition and health in India. What is less known is the extent to which these individual-level risk factors are geographically distributed. Assessing the geographic distribution, especially at multiple levels, matters as it can inform where, and at what level, interventions should be targeted. The three levels of significance in the Indian context are villages, districts, and states. Thus, the purpose of this paper was to (a) examine what proportion of the variation in 21 risk factors is attributable to villages, districts, and states in India and (b) elucidate the specific states where these risk factors are clustered within India. Using the fourth National Family Health Survey dataset, from 2015 to 2016, we found that the proportion of variation attributable to villages ranged from 14% to 63%, 10% to 29% for districts and 17% to 62% for states. Furthermore, we found that Bihar, Jharkhand, Madhya Pradesh, and Uttar Pradesh were in the highest risk quintile for more than 10 of the risk factors included in our study. This is an indication of geographic clustering of risk factors. The risk factors that are clustered in states such as Bihar, Jharkhand, Madhya Pradesh and Uttar Pradesh underscore the need for policies and interventions that address a broader set of child malnutrition determinants beyond those that are nutrition specific.

Anganwadi worker time use in Madhya Pradesh, India: a cross-sectional study.

BACKGROUND: Anganwadi Workers (AWWs) are a group of 1.4 million community health workers that operate throughout rural India as a part of the Integrated Child Development Services program. AWWs are responsible for disseminating key health information regarding nutrition, family planning, and immunizations to the women and children in their catchment area, while maintaining detailed registers that track key beneficiary data, updates on health status, and supply inventory beneficiaries. There is a need to understand how AWWs spend their time on all of these activities given all of their responsibilities, and the factors that are associated with their time use. METHODS: This cross-sectional study conducted in Madhya Pradesh, collected time use data from AWWs using a standard approach in which we asked participants how much time they spent on various activities. Additionally, we estimated a logistic regression model to elucidate what AWW characteristics are associated with time use. RESULTS: We found that AWWs spend substantial amounts of time on administrative tasks, such as filling out their paper registers. Additionally, we explored the associations between various AWW characteristics and their likelihood of spending the expected amount of time on preschool work, filling out their registers, feeding children, and conducting home visits. We found a positive significant association between AWW education and their likelihood of filling out their registers. CONCLUSIONS: AWWs spend substantial amounts of time on administrative tasks, which could take away from their ability to spend time on providing direct care. Additionally, future research should explore why AWW characteristics matter and how such factors can be addressed to improve AWWs' performance and should explore the associations between Anganwadi Center characteristics and AWW time use.

Role of Pulse Oximetry and Ankle Brachial Index in Diagnosis of Lower Limb Artery Disease (LEAD) in Patients with Coronary Artery Disease.

BACKGROUND: Lower extremity arterial disease is common disorder affecting large number of peoples and is frequently asymptomatic. Currently ABI is used as screening test for LEAD, which is time consuming and requires special instrument for measurement. We compare the role of pulse oximetry, ABI and its combination in diagnosis of LEAD. METHODS: Total 224 patients (448 limbs) were enrolled in the study. Complete history, examination was done. Pulse oximetry of all limbs and ABI of both lower limbs were measured. CT angiography and pulse Doppler was done to diagnose LEAD. RESULTS: Pulse oximetry was found to have sensitivity of 60.5%, specificity of 95.9% positive likelihood ratio 14.93 and negative likelihood ratio 0.41. ABI was found to have sensitivity of 69.7%, specificity of 97.3%, positive likelihood ratio 25.8 and negative likelihood ratio 0.32. But when both are combined, sensitivity increases to 84.2%, specificity decreases to 91.9%, positive likelihood ratio decreases to 10.39 and negative likelihood ratio decreases to 0.17. CONCLUSION: Our study suggests that pulse oximetry is simple and non-invasive test that provides quick result which is at least as accurate as ABI and thus is an easy alternative/ additional method for the screening of LEAD. However when used in combination with ABI the sensitivity for the detection of LEAD increases.

Prevalence of zero-sanitation in India: Patterns of change across the states and Union Territories, 1993-2021.

Background: Ensuring universal access to safe sanitation by 2030 is a development priority for India. Doing so can help ensure improved physical and mental health outcomes. While the proportion of people in India with safe sanitation has risen dramatically over the past thirty years, much less is known about who has been most at risk for not having access to safe sanitation across India's states and Union Territories (UT) over this time period. We introduce the concept of zero-sanitation to fill this gap. Methods: Data from five National Family Health Surveys (NFHS) conducted in 1993, 1999, 2006, 2016, and 2021 from 36 states and UT were used for this study. The study population consisted for all household individuals regardless of age in each survey round. Zero-sanitation was defined as those who have no access to a household toilet, and thus defecate in the open. We analyzed the percent prevalence of zero-sanitation in every state / UT at each time period in both urban and rural communities, as well as the population headcount burden in 2021. We calculated the absolute change on an annual basis to assess the change in percentage points of zero-sanitation across time periods at the all-India and state / UT levels. Results: The all-India prevalence of zero-sanitation declined from 70.3% (95% confidence interval (CI) = 70.2%-70.5%) in 1993 to 17.8% (95% CI = 17.7%-17.9%) in 2021. The median percent prevalence of zero-sanitation across states and UTs was 65.9% in 1993. By 2021, the median percent prevalence of zero-sanitation across states and UTs was 5.7%. This reduction corresponded with a reduction in the between state / UT inequality in zero-sanitation. Nevertheless, as of 2021, the prevalence of zero-sanitation was still above 20% in Bihar, Jharkhand, Madhya Pradesh, Odisha, Rajasthan, and Uttar Pradesh. Additionally, as of 2021, almost 92% of individuals who were defecating in the open were experiencing zero-sanitation. Zero-sanitation remains most common in states such as Bihar, Punjab, Uttar Pradesh, and Assam. Nevertheless, at this current rate of improvement, every state and UT except for Sikkim and Chandigarh are on track to end open defecation by 2030. Conclusions: The concept of zero-sanitation is a useful tool in helping policy makers assess the extent to which sanitation coverage remains incomplete. When viewed through this lens, we see that open defecation remains most common among those who do not have a toilet. Addressing the myriad social determinants of sanitation access can help fill these gaps and ensure equitable sanitation coverage throughout India.

Food deprivation among adults in India: an analysis of specific food categories, 2016-2021.

Background: Adult undernourishment remains pervasive throughout India, and often results from food deprivation, which refers to the inadequate consumption of foods with caloric and nutrient significance. Therefore, understanding the extent to which food groups are missing from an individual's diet is essential to understanding the extent to which they are undernourished. Methods: We used data from two National Family Health Surveys conducted in 2016 and 2021 for this cross-sectional analysis. The study population consisted of women and pregnant women between the ages of 15-49, and men between the ages of 15-54. We examined shifts in the percentage of people not consuming dairy, pulses/beans/legumes, dark leafy green vegetables, fruits, eggs, and fish and meat among women, pregnant women, and men between the two time points. We also examined these patterns by household wealth and education, two important markers of socioeconomic status. Findings: Overall, we found that fewer women, pregnant women, and men were not eating each of the six food groups in 2021 than in 2016. Additionally, the gap in food group consumption between women, pregnant women, and men in the lowest and highest socioeconomic groups shrank between 2016 and 2021. Yet, food group deprivation remained most prevalent among those in the lowest socioeconomic groups. The two exceptions for this were for eggs and meat/fish. Nevertheless, the majority of India's poorest and least educated adults are not consuming high-quality protein sources, including dairy, the consumption of which is far more common among wealthier and more educated Indian adults. Interpretation: Our results show that fewer adults were not consuming important food groups in 2021 than in 2016. However, many of India's poorest and least educated adults are still not consuming high-quality sources of protein or fruits, two food groups that are essential for good health. While adults might be getting protein and nutrients from pulses, legumes, beans, and other vegetables, efforts are needed to improve affordability of, and access to, high-quality sources of protein and fruits.

Small area variations in four measures of poverty among Indian households: Econometric analysis of National Family Health Survey 2019-2021.

India has seen enormous reductions in poverty in the past few decades. However, much of this progress has been unequal throughout the country. This paper examined the 2019-2021 National Family Health Survey to examine small area variations in four measures of household poverty. Overall, the results show that clusters and states were the largest sources of variation for the four measures of poverty. These findings also show persistent within-district inequality when examining the bottom 10th wealth percentile, bottom 20th wealth percentile, and multidimensional poverty. Thus, these findings pinpoint the precise districts where between-cluster inequality in poverty is most prevalent. This can help guide policy makers in terms of targeting policies aimed at reducing poverty.

The Association between Anthropometric Failure and Toilet Types: A Cross-Sectional Study from India.

Sustainable Development Goal 6.2 aims to end open defecation by 2030 by ensuring universal access to private household toilets. However, private toilets might not be feasible for poor households. As a result, policy makers and academics have suggested well-managed shared sanitation facilities as an alternative solution. Less is known about the associations between shared sanitation use and health. Using data from the fifth round of the National Family Health Survey from 2019 to 2021, we estimated the association between usual defecation location and child anthropometry outcomes among children under 2 years in India. The primary exposure was usual defecation location at the household level. We compared both shared improved toilet use and open defecation to private, improved toilet use. We used linear regression to estimate the associations between the exposures and linear outcomes: height-for-age Z-score, weight-for-height Z-score, and weight-for-age Z-score. We used Poisson regression with a log link to estimate the prevalence ratios of stunting, wasting, and underweight. After controlling for environmental, maternal, socioeconomic, and child confounders, we found no differences in six child anthropometry outcomes when comparing shared toilet use or open defecation to private toilet use. This finding was consistent across both urban and rural households. Our findings confirm the null associations between private toilet use and child growth found in previous studies, and that this association does not vary if the toilet is being shared. Future research should examine these differences between private and shared toilets in the context of other health outcomes.

The Associations between Member of Parliament Characteristics and Child Malnutrition and Mortality in India.

Child health outcomes vary between Parliamentary Constituencies (PCs) in India. There are a total of 543 PCs in India, each of which is a geographical unit represented by a Member of Parliament (MP). MP characteristics, such as age, gender, education, the number of terms they have served, and whether they belong to a Scheduled Caste or Scheduled Tribe, might be associated with indicators of child malnutrition and child mortality. The purpose of this paper was to examine the associations between MP characteristics and measures of child malnutrition and mortality. We did not find any meaningful associations between MP characteristics and child anthropometry, anemia, and mortality. Future research should consider the size of a constituency served by an MP along with MP party affiliations as these factors might help explain between-PC variations in child health outcomes. Our findings also underscore the need to better support female MPs and MPs from marginalized caste and tribal groups.

"Someone Should be There to Take Care of It": A Case Study of Users' Views of Managed Shared Sanitation Facilities in Jharkhand, India.

The Sustainable Development Goals have set an ambitious target to end open defecation by 2030 by building private household toilets. These toilets are categorized based on quality indicators. However, toilets that are shared among households are considered "limited," disincentivizing governments and implementers from investing in this infrastructure despite being more appropriate in certain contexts. Furthermore, unlike private toilets, shared toilets are not distinguished based on their quality. As such, there is a need to understand what attributes constitute well-managed shared toilets. These types of facilities could play an important role in helping people move up the sanitation ladder away from open defecation in certain contexts. Therefore, we conducted 41 one-on-one in-depth interviews with users of managed shared sanitation facilities. We found that maintenance and accessibility are key indicators of well-managed shared sanitation. Maintenance includes the provision of water for flushing and self-cleaning, cleaning, and high-quality built infrastructure. Accessibility is defined by the distance people have to walk to reach the facility, the amount of time they have to wait in line, and design features of the facility that encourage use. These findings could help distinguish managed versus unmanaged shared sanitation and could help inform global sanitation policies.

Small Area Variations in Dietary Diversity Among Children in India: A Multilevel Analysis of 6-23-Month-Old Children.

Dietary diversity is an important indicator of child malnutrition. However, little is known about the geographic variation of diet indicators across India, particularly within districts and across states. As such, the purpose of this paper was to elucidate the small area variations in diet indicators between clusters within districts of India. Overall, we found that clusters were the largest source of variation for children not eating grains, roots, and tubers, legumes and nuts, dairy, vitamin A-rich vegetables and fruits, and other vegetables and fruits. We also found positive correlations between the district percent and cluster standard deviations of children not breastfeeding or eating grains, roots, and tubers, but negative correlations between the district percent and cluster standard deviation for the remaining seven outcomes. These findings underscore the importance of targeting clusters to improve child dietary diversity.

Bronchial artery embolization: A gratifying life-saving procedure.

BACKGROUND: Bronchial artery embolization (BAE) is an urgent life-saving procedure in patients with massive hemoptysis. MATERIAL AND METHODS: This was a single center observational study wherein patients presenting with hemoptysis were evaluated and underwent BAE. Initially, a descending thoracic aortogram was performed to identify culprit vessels followed by selective catheterization of the involved vessels. Abnormal bronchial artery morphology included hypertrophied and tortuous bronchial artery (BA), focal hyperemia and hypervascularity, shunting into pulmonary artery or vein, extravasation of contrast into the lung parenchyma/cavity and BA aneurysms. Selective embolization was done using either gelfoam or polyvinyl alcohol particles. Post-procedure, follow-up was done at one month and six months with outcomes defined in terms of recurrence of hemoptysis. RESULTS: A total of 187 patients underwent BAE with post-tubercular sequalae being the most common diagnosis in 157 (84%) followed by idiopathic bronchiectasis in 19 (10.2%) and aspergilloma in 7 (3.7%). A total of 246 vessels were embolized with right sided BA being more commonly involved as compared to left [143 (76.5%) vs. 35 (18.7%); P < 0.0001]. Complete resolution was observed in 183 (97.8%) 24 hours post procedure. Recurrence was reported in 34 (18.2%) patients with higher frequency in diabetics, patients with active tuberculosis and presence of aspergillomas. Multi-variate logistic regression analysis showed that diabetes, presence of an aspergilloma and feeding vessels from internal mammary artery were independent predictors of recurrent hemoptysis. Most of the complications were minor except paraparesis observed in two patients. CONCLUSION: BAE is a safe and effective procedure for the treatment of hemoptysis of different etiologies.

Understanding Open Defecation in the Age of Swachh Bharat Abhiyan: Agency, Accountability, and Anger in Rural Bihar.

Swachh Bharat Abhiyan, India's flagship sanitation intervention, set out to end open defecation by October 2019. While the program improved toilet coverage nationally, large regional disparities in construction and use remain. Our study used ethnographic methods to explore perspectives on open defecation and latrine use, and the socio-economic and political reasons for these perspectives, in rural Bihar. We draw on insights from social epidemiology and political ecology to explore the structural determinants of latrine ownership and use. Though researchers have often pointed to rural residents' preference for open defecation, we found that people were aware of its many risks. We also found that (i) while sanitation research and "behavior change" campaigns often conflate the reluctance to adopt latrines with a preference for open defecation, this is an erroneous conflation; (ii) a subsidy can help (some) households to construct latrines but the amount of the subsidy and the manner of its disbursement are key to its usefulness; and (iii) widespread resentment towards what many rural residents view as a development bias against rural areas reinforces distrust towards the government overall and its Swachh Bharat Abhiyan-funded latrines in particular. These social-structural explanations for the slow uptake of sanitation in rural Bihar (and potentially elsewhere) deserve more attention in sanitation research and promotion efforts.

Sanitation in Rural India: Exploring the Associations between Dwelling Space and Household Latrine Ownership.

In 2017, the Joint Monitoring Programme estimated that 520 million people in India were defecating in the open every day. This is despite efforts made by the government, Non-Governmental Organizations (NGOs), and multilaterals to improve latrine coverage throughout India. We hypothesize that this might be because current interventions focus mostly on individual-level determinants, such as attitudes and beliefs, instead of considering all possible social determinants of latrine ownership. Given this, we ask two questions: what is the association between the amount of dwelling space owned by households in rural India and their likelihood of toilet ownership and what proportion of the variation in household latrine ownership is attributable to villages and states? We used multilevel modeling and found significant associations between the amount of household dwelling space and the likelihood of latrine ownership. Furthermore, considerable variation in latrine ownership is attributable to villages and states, suggesting that additional research is required to elucidate the contextual effects of villages and states on household latrine ownership. Thus, sanitation interventions should consider household dwelling space and village and state context as important social determinants of latrine ownership in rural India. Doing so could bolster progress towards Sustainable Development Goal (SDG) 6.

Effects of an mHealth intervention for community health workers on maternal and child nutrition and health service delivery in India: protocol for a quasi-experimental mixed-methods evaluation.

INTRODUCTION: Millions of children in India still suffer from poor health and under-nutrition, despite substantial improvement over decades of public health programmes. The Anganwadi centres under the Integrated Child Development Scheme (ICDS) provide a range of health and nutrition services to pregnant women, children <6 years and their mothers. However, major gaps exist in ICDS service delivery. The government is currently strengthening ICDS through an mHealth intervention called Common Application Software (ICDS-CAS) installed on smart phones, with accompanying multilevel data dashboards. This system is intended to be a job aid for frontline workers, supervisors and managers, aims to ensure better service delivery and supervision, and enable real-time monitoring and data-based decision-making. However, there is little to no evidence on the effectiveness of such large-scale mHealth interventions integrated with public health programmes in resource-constrained settings on the service delivery and subsequent health and nutrition outcomes. METHODS AND ANALYSIS: This study uses a village-matched controlled design with repeated cross-sectional surveys to evaluate whether ICDS-CAS can enable more timely and appropriate services to pregnant women, children <12 months and their mothers, compared with the standard ICDS programme. The study will recruit approximately 1500 Anganwadi workers and 6000+ mother-child dyads from 400+ matched-pair villages in Bihar and Madhya Pradesh. The primary outcomes are the proportion of beneficiaries receiving (a) adequate number of home visits and (b) appropriate level of counselling by the Anganwadi workers. Secondary outcomes are related to improvements in other ICDS services, and knowledge and practices of the Anganwadi workers and beneficiaries. ETHICS AND DISSEMINATION: Ethical oversight is provided by the Committee for the Protection of Human Subjects at the University of California at Berkeley, and the Suraksha Independent Ethics Committee in India. The results will be published in peer-reviewed journals and analysis data will be made public. TRIAL REGISTRATION NUMBER: ISRCTN83902145.

Intrinsic and instrumental perspectives to sanitation.

Public health interventions are often implemented because they are a means to an end. For example, improving population-level health outcomes is a key step towards improving social and economic outcomes, too. But what is often overlooked is the fact that a given public health intervention might be the end in itself. In other words, a given intervention might be worth investing in even if there are zero returns from investing in it. This intrinsic value, however, is often overlooked. In this commentary, we look specifically at sanitation, and why the development community should motivate sanitation interventions using an intrinsic value perspective. We also extend the conversation to why there needs to be a fundamental shift away from demand-side interventions to supply-side interventions. In doing so, we hope to offer a more equitable perspective to health and development.

Prediction of Angiographic Extent of Coronary Artery Disease on the Basis of Clinical Risk Scores in Patients of Unstable Angina.

BACKGROUND: The correlation of clinical risk predictors and clinical risk scores: Thrombolysis in Myocardial Infarction (TIMI), Platelet Glycoprotein IIb-IIIa in Unstable Angina, Receptor Suppression Using Integrilin Therapy (PURSUIT) and Global Registry of Acute Coronary Events (GRACE) scores in Unstable Angina with angiographic extent of Coronary Artery Disease (CAD) is not known. AIM: To know the correlation of clinical risk scores with angiographic extent of coronary artery disease. MATERIALS AND METHODS: This was a hospital based single centre, cross-sectional, observational, descriptive study conducted at a tertiary care teaching institute. One hundred and sixty patients with acute unstable angina were evaluated for presence of 9 clinical predictors and their 3 risk scores were calculated. All patients underwent coronary angiography. Correlation with Modified Gensini score and percentage stenosis in culprit artery was done. STATISTICAL ANALYSIS: Data were summarized in the form of Mean, Standard Deviation and Proportions. Multiple linear regressions, Student's t-test and Pearson's coefficient 'r' were also used. RESULTS: Use of aspirin, age >= 65 years & presence of Congestive Heart Failure (CHF) were stronger predictors of Modified Gensini score. Presence of elevated enzymes and age >65 years were more significant predictors of percentage stenosis of culprit artery. GRACE score had better correlation with Modified Gensini score, PURSUIT score had more correlation with percentage stenosis in culprit artery. CONCLUSION: Use of Aspirin, age >= 65 years, presence of CHF and presence of elevated enzymes are stronger predictors of extent of CAD. Hence we recommend that these factors be given more importance. GRACE and PURSUIT risk scores had more correlation with angiographic extent of CAD.

Surgical management of fractured orthodontic mini- implant- a case report.

The idea of absolute anchorage has always been an elusive goal for clinicians. Orthodontic mini-implants or temporary anchorage devices allow tooth movements previously thought to be impossible or difficult. Although extensive literature exists on use of temporary anchorage devices, their failures have been hardly focused upon, especially implant fracture. The following case report describes successful management of fractured orthodontic mini-implant.

Palatal rugae and their role in forensic odontology.

Establishing a person's identity can be a difficult task in cases of traffic accidents or in mass disaster situations. The records collected to identify a decedent should be accurate and totally inclusive of objective findings. When a victim has no teeth, information for use in personal identification based on methods available in forensic odontology is much more limited than in the case of dentate victims. Palatal rugae have been considered relevant for human identification due to its stability, which is equivalent to the fingerprint, in that it is unique for each ruga pattern. Palatal rugae appear to possess the features of an ideal forensic identification parameter, that is, uniqueness, postmortem resistance, and stability. The purpose of this article was to review the literature, in order to determine if there is enough evidence to establish the use of palatal rugae in dental identification.
